Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
27-05-2014 to 13-06-2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
other guidance covered: ISO 304-1985; UNE 55-50
GLP compliance:
no
Type of method:
OECD harmonised ring method
Surface tension:
29.8 mN/m
Temp.:
25 °C
Conc.:
21 mg/L

Age of the surface of the test substance solution:

1hours

Surface tension (25°C):

63.53 mN/m (1 mg/I)

58.66 mN/m (2 mg/I)

41.65 mN/m (5 mg/I)

34.08 mN/m (10 mg/I)

29.80 mN/m (21 mg)

Conclusions:
The surface tension of the test substance was determined according to OECD115 (ring method, determination of CMC) for several concentrations. At 21 mg/l the surface tension was 29.8 mN/m.
Executive summary:

The surface tension of the test substance was determined according to OECD115 (ring method, determination of CMC) for several concentrations. At 21 mg/l the surface tension was 29.8 mN/m.

Description of key information
